2 Claims.

This invention relates to a book and particu- 1arly to bookconstructions, the individual sheets whereof are independent of eachother but bound together to form a book. The book when open Will 1ieabsolutely fiat and the individual pages thereof Will be accessiblesubstantially from edge to edge. The amount of material a1ong the boundedge which is utilized for associating the pages in their book formationneed not exceed a quarter of an inch and preferably approximatelythreesixteenths of an inch, but nevertheless securely uniting the sheetsinto book formation. This invention is particularly useful in connectionWith binding together catalogs circulars, and photop1ints of printed orwritten matter, which are usually printed upon fair1y heavy paper andoften bear printed or illustrative matter c1ose t the binding edges. Itmay also be utilized in connection With blank books which are providedfor keeping memoranda or records, particularly entry books which areru1ed fro-m edge to edge.

The pages comprising the book are individual sheets but united by thebinding element, which binding element, although permanently united withthe pages, is, nevertheless, independently movable as the book is openedor closed, reducing the friction at the points where the sheets and thebind.er unite, thereby -preserving the pages against tearing. The bookas a whole is flexible and the binding element readily fiexes with thebook, particularly in a lengthwise direction, but readily resumes itsnormal position by reason of its special features of construction.

The binder of this invention is exceedingly strong and not readilydeformable permanently during the ordinary use of the book and. theentire binder, if fiexed, Will readily return to its normal shape,tending to support the book as a stiffening element and not beingsubject to permanent deformation by use in handling and when the bookstands on edge.

In the drawing, Fig. 1 represents a book comprising a multiplicity ofsheets bound together with the binder element of this invention; Fig. 2is a cross section on the 1ine 22 of Fig. 4; Fig. 3 is a side view of aportion of the book and. binder from the left of Fig. l; Fig. 4 is anenlarged view from the top of Fig. l; Fig. 5 is an enlarged view of oneof the page-supporting elements and portions of the diverging tie rods;Fig. 6 is a section 011 the 1ine 6-6 of Fig. 2.

A bound book comprises a multiplicity of pages i, -provided with holes 2along the binding edge of the book. The holes 2 may be of any desiredshape preferably rectangular or oval. The binder 3 is associated. Withthe book by threading the pages into the page-supporting elements cf thebinder. The binder 3 comprises a multiplicity of fastener elements 4,spaced apart a suitable distance and united With the tie rods 5. Eachfastener element 4 consists of two members 6 and l, f0rmed 011 the areof a circle, fiat from the point 8 of divergence, from the tie rod, tothe tip 9 of the fastener members 6 and 7. The free ends of each pair offastener members 6 and 1 are joined by the tip or nose 9, which, at itsextreme end l0 is rounded and. narrower than the distance across thefastener members 6 and l. Each pair cf fastener members, as illustratedin Figs. 5 and 6, has the appearance of being made of a single length offiat stock but actually the fastener members comprise two separatesections of materia1 lying quite close1y together. It is preferred tohave the inside edges of the two members 6 and. 7 in contact, but thereis a tendency for these members t0 separate slightly in use. Thefastening elements do not comprise a complete circle but, to thecontrary, extend only from the point 8 to the b-ase of the tip 9. Thefastening elements 6 and l terminate at the point of divergence 8 andadjoining fastening members are united together by the tie rods 5comprising a single course of metal, round in cross section, as shown atl! in Fig. 2. If desired, the tie rods may be bent in a slight are, asshown in Fig. 5, to provide a space I2 which permits the tip 9 to bebrought quite close to the surface 015 the tie rods, as is illustratedin Fig. 5.

The individual pages of the book are threaded over the rounded tip 9 andultimatelj over the body of the fastener members 6, l. This may be doneWhi1e the tip 9 is spaced some distance from the tie rods 5 andthereafter the fastener element is deformed to bring the tip 9 in closerelation t0 the tie rods.

The binders are preferably made initially of round wire and after theelements are formed but while still in the fiat condition, the fastenerelements 6 and l are flattened either by a pinching or stampingoperation on an anvi1 or by other suitable tools. The flatteningoperation is so sonducted that neither the tie rods 5 nor the tip 9 areflattened. During the course of the fiattening operation the otherwiseslightly flexible and readi1y bendable Wire is compacted andstrengthened.

I claim:

1. A book -comprising a multiplicity of pages having a series of holesalong the binding edge thereof, a binder, said binder being made of a,single length of continuous metal formed to promembers of the binderpassing through said holes in seid pages'.

2. A book according 120 elaim 1v in which the nose of the bindingelement is narrower than the distance across the flattened portions ofthe duplex ringlike members and the tie rode associated, With eachflattened portion, diverging in opposite directions from the fiattenedportions and forming a space for the entry of the extreme end of saidnose to secure the pages 0f the book 10 from escape from said binder.
